Clean power for sustainable water
treatment operations
Comsys ADF technology cleans the power your plant uses to treat water and wastewater,
improving sustainability, securing critical infrastructure and saving taxpayer money
while optimizing IEEE 519 compliance.
Lowering the costs of clean water
Electricity consumption for water supply and wastewater treatment is the second highest operation cost after labour, and can account for 30%–40% of a municipality’s energy bill. It also has a significant environmental impact—improving energy use efficiency could measurably reduce municipalities’ overall carbon footprint. Comsys ADF is a power quality filter technology that improves the efficiency of your treatment plant’s energy grid. Thanks to its lower upfront investment and ongoing energy use costs, equipping your plant for grid compliance can also be a cost-effective investment in sustainable public infrastructure.
Power quality solutions for optimal efficiency

Compliance that pays for itself
Power quality compliance regulation is a requirement for water and wastewater treatment facilities. With Comsys ADF, that requirement can be an investment in energy efficiency that lowers operational energy costs of your pumps by 5% -significant cumulative savings that can be used to offset operational costs, or be re-invested in new plants and upgrades as needed.

Secure critical infrastructure
Comsys ADF lowers the impact of harmonics on the energy grid, while protecting your electrical equipment from the overheating, flickering and accelerated wear that puts critical equipment at risk. It supports the predictable uptime and reliability of operational capacity that protects the environment while earning public trust.

New sustainability opportunities
For many municipalities, cost and environmental sustainability have increased in importance as public works priorities. Comsys ADF offers a powerful way to ensure your treatment facilities use energy at least 5% more efficiently at no extra cost, significantly lowering your overall carbon footprint.

Designed with your growth in mind
Comsys ADF is mounted parallel to variable frequency drives, rather than on them—allowing one filter to be configured for multiple drives. This lowers space requirements and capital costs for redundancy planning, while ensuring the modularity to upgrade simply, cost-effectively and in compliance as needed.

3 advantages for you
1. Save space
Water treatment plants often do not have the luxury of building from scratch. Rather, they must often upgrade with retrofits. When working with an existing physical infrastructure, it’s important to have a solution with a minimal space requirement. ADF products provide powerful compensation in a compact form. In other words, you can do more with less.
2. Achieve redundancy
A chief concern in water treatment is the risk of contamination. These plants provide a critical function for societies around the world. And while this reliance is invisible when processes are working well, society definitely takes notice when something goes wrong. ADF helps prevent drastic problems such as equipment malfunction, unexplained interruptions, and unplanned stops.
3. Enable energy savings
VSDs are crucial for running a water treatment plant, as well as reducing a plant’s energy consumption. ADF enables the plant to run on VSDs without problems by essentially removing the problems that would hinder the VSDs from working their best.
And due to the ability to be installed in-parallel, ADF technology enables lower energy losses than conventional compensation technology.
